**The minimum and maximum values of the mechanical properties vary according to the final heat treatment.
** Trademark
1) For design temperatures above 427 ºC tests shall be performed at 650 ºC. For studs and nuts as per ASTM A-276 and MONEL the material applied is the same for both. However, such elements should be requested as per ASTM A-453, nuts should be manufactured according to ASTM A-194 Gr.B8T. |
